Representation of Data (Graphs)
Majority of people or groups of people use graphs to portray their data that they have calculated. These graphs can be similar or different in a lot of way. With graphs, a person can tell if the display is reliable data or not. There are specific details that one can find to ensure that the graph has data that is correct.
